STATION-INDICATOR.

SPECIFICATION forming part of Letters Patent No. 382,006, dated May '1;1888.

Application filed January 13, 1888. Serial No. 260,671.

(No model.)

To alt whom it may concern:

Be 1t lrnown that I, KINGSBURY S. NIoKER- soN, a c1t1zen of the UnitedStates, residing at Passaic, in the county of Passaic, State of NewJersey, have invented certain new and; useful Improvements inStation'lndicators, of which the following is aspecification, referencebeing hadtherein to the accompanying drawings My invention relates toimprovements in that class of station-indicators in which the names boxbeing broken away to show a portion of v ment therewith.

the interior and the operating mechanism. Flg. 2 is a longitudinalvertical section of the same. Fig. 3 is an end view of the same open toshow the operating mechanism. Fig. 4 is a front view of theoperating-pulley and one of the gear-wheels provided with a ratchetwheel(in section on line a: of Fig. 2) and the double pawl having one of itsarms in engage- Fig. 5 is a perspective view, on a larger scale, of theoperating-pulley. Fig. 6 is a perspective view of the double pawl. Fig.7 is a transverse section of one of the rollers carrying the printedband of the indicator.

In said drawings, A represents the rear board of the indicator, by whichit can be secured to the end of a car.

A represents-the front thereof, provided with an opening covered byglass, A through which can be seen the names of streets or of stat-ionsprinted or painted on a band, B, of textile fabric or of other suitablematerial, that can be wound on rollers O and C. These rollers are formedof two halves, one of which is provided with a longitudinal groove, 0,to receive a tongue, 0 extending the length of the other, and betweenthese two halves and their tongue and groove one end of the band B isclamped and firmly retained; but these two halves are easily separatedwhen it is desired to change or to renew this hand. To retain the twohalves of the rollers united together, one end is screw-threaded and isreceived in an internally'screw-threaded cap, D, having on its outer enda journal, 01, that is received in an open bearing in the end A of theframe, where it is retained either by a pin, a, or by a pivoted hook, a,resting upon it, but from which bearing thejournal can be lifted when itis desired to change the band of names. The opposite end of the rollersis made square and is received in a cap, E, having a similar squarejournal for that end of the roller, and is received in a bearing in theend A of the frame. This cap E has a collar, 6, to bear against theouter face of the boardA and prevent any end motion of the cap in onedirection. This cap is also provided on one end with aspindle, the body6 of which is square to receive the square socket in the hub of itsoperating gear;wheel E; but the outer end of said spindle is cylindricaland forms a journal, 6 that is received in a bearing made in the endboard, A, of the frame.

Half-way between the bearings for the spindles or journals 6 the boardsA A have a square perforation to receive the square ends f of ajournal,F, having on the middle of its length a cylindrical enlargement, f",that constitutes the journal for the operating-pulley G, and on eachside of the enlargementf (between it and the square endsf) the shaft Fis cylindrical to act as a journal for the cog-wheels H and H, uponwhich they can revolve in either direction under the impulse of adouble-arm pawl, I, pivoted in an angular radial recess, of the pulleyG. Said recess 9, being wider than the angular end i of the pawl,permits either one of the arms 1' i of said pawl to engage with theteeth of the ratchet-wheel It is, secured to one side and forming a partof the cog'wheels H H lhe pawl Iis centrally secured at i to straddlethe enlargement f of the journal F, and is free to work in its recess 9when the pulley G is revolved under the impulse given by the conductoror other railwayoflicer to the endless band L, passing with sufficientfriction in the peripheral groove of said recess, but a cylindricalperiphery to act as a pulley. This endless band may be of suitablelength to be conveniently grasped whatever may be the location of theindicator. \Vhcn the car is advancing in one direction of its route, theconductor pulls the hand L in the direction of the arrow 1 in Fig. 4,after having passed a station, to bring in view the name of the nextstation. \Vhen he is returning on his route, he pulls the band L in thedirection of the arrow 2 and the pawl I is automatically reversed fromengagement with one ratchetwheel to engage with the other.

Having now fully described my invention, I claim- 1. In astation-indicator, the combination of two rollers made in two halves,one of which is tongued and the othergrooved, an internallyscrew-threaded cap inclosing one end thereof and a square-soeketed capinelosing the other, said square socket having a square spindle and acylindrical journal at the end, gear-wheels mounted upon the squarespindles, and intermediate gears uniting them, substantially as and forthe purpose described.

2. The combination of two rollers carrying a printed hand between them,each having a square spindle at one end, a gear-wheel upon each spindle,ajournal, F, and two gear-wheels thereon located between the gears uponthe spindles and carrying ratchet-Wheels, a pulley, G, inclosing saidratchet-wheels and having an angular recess, 1, therein, and a pawlhaving an angular end, 13, located in said recess and having also twoarms for engagement with said ratchetwvheels, substantially asdescribed.

In testimony whereof I affix my signature in presence of two witnesses.
